   This method compresses all files in the Phar archive using bzip2 compression.
   The <a href="ref.bzip2.html" class="link">bzip2</a> extension must be enabled to take
   advantage of this feature.  In addition, if any files are already compressed using
   gzip compression, the <a href="ref.zlib.html" class="link">zlib</a> extension must be enabled in order
   to decompress the files prior to re-compressing with bzip2 compression.
   As with all functionality that modifies the contents of
   a phar, the <a href="phar.configuration.html#ini.phar.readonly" class="link">phar.readonly</a> INI variable
   must be off in order to succeed.
